Hi Giovanni,

We use swapfiles.

We are running on Ubuntu.

I don't know how to turn on the collectd.log nor how to adjust loglevel to DEBUG.

Can you advise?

Very strangely, 3 of the 18 systems do report the information.

All 18 have collectd running and /etc/collectd/plugins/swap.conf present.

Only these items are being reported for the 15:


but not


like the three which report all five of the above swap plugin metrics.

I am mystified. Please let me know how I can turn on debugging.

I believe the version of collectd being used is 5.4.

Has anyone seen that kind of partial?

I have not.  Are you running it on Linux?  Are you using a physical swap device or a swapfile? Is there any related output in the collectd.log?  You can also temporarily bump up the loglevel to DEBUG.
